Overview
- Anthropic ended negotiations to acquire Israel‑based Decart for about $6 billion, a development reported Tuesday, September 8, 2026, that halts months of advanced talks.
- The proposed deal was structured mainly in Anthropic stock and valued Decart at roughly a 50% premium over its May private valuation of about $4 billion.
- Decart makes chip‑optimization software that cuts the cost of AI training and inference, and it raised about $300 million in May as part of roughly $450 million total funding.
- Decart’s three founders reportedly retain a majority stake, Nvidia was a May investor and was said to have shown competing interest, and those factors gave Decart leverage in talks.
- The pullback forces Anthropic to recalibrate how it secures compute efficiency before an expected IPO and leaves room for alternative bids, partnerships, or renewed talks with cloud and chip partners.
